55Large complex programs are composed of many small routines
56that implement abstractions for the routines that call them.
57To be useful, an execution profiler must attribute
58execution time in a way that is significant for the 
59logical structure of a program
60as well as for its textual decomposition.
61This data must then be displayed to the user
62in a convenient and informative way.
63The \fBgprof\fP profiler 
64accounts for the running time of called routines
65in the running time of the routines that call them.
66The design and use of this profiler is described.
